WolfVision VZ-27 User Manual - Handbuch (Seite 9)

PRESET FUNCTION
WolfVision Visualizers offer the possibility of programming three presets for the functions: Zoom, Focus, Iris,
Light, Image, Text, Macro, Mirror position*, Positive/Negative and Black/White. They can be recalled by pressing
one of the three PRESET keys (#14) on the control panel or the remote control.
This function is very useful for example if a user requires one preset for papers on the working surface, one for
working with slides (bottom light) and one for an object placed in front of the unit. During his presentation the
user just has to press one of the PRESET keys when he changes from one object to the other.
For programming a preset just adjust every function as required and then keep one of the PRESET keys pressed
for more than 2 seconds. The on-screen menu tells you when the preset is stored.
When the presets are stored as mentioned above, all current settings like zoom-, focus- or image position are
stored. Contrary to this, a user also has the opportunity to assign only specific functions such as "Image on/off",
"Iris open/close", "Negative", "Negative/Blue", "Black/White" etc. to a PRESET key. This can be done in the on-
screen menu of the Visualizer (see page 14).
Quickly pressing: Recalling a preset
More than 2 seconds: Saving a new preset
* You can select in the unit's on-screen menu if the mirror position should
be stored in a preset or not (see page 14). Default is: YES.
AUTOIRIS / MANUAL IRIS
WolfVision Visualizers are equipped with autoiris. That means that the brightness of the camera image adjusts
automatically. Using the IRIS keys (#24) the autoiris function is switched off. In this mode the Iris can be adjusted
manually. When using the ZOOM keys (#13) the autoiris function is switched on again. Before the iris closes
completely, the Visualizer automatically dims the light.
The standard auto iris level can be set brighter or darker in the unit's menu - see page 14 and on-screen help.
RESET FUNCTION / POWER-ON PRESET
When switching on the unit the "Power-on Preset" is activated (=Top light on, Zoom at 210 x 148mm, Focus on
the working surface level, Mirror center). This function can be switched off in the units menu (#23) if required -
see help menu (#25). This "Power-on Preset" can also be recalled during operation of the unit by pressing the
RESET key (#20)
USB-PORT
SWITCHABLE OUTPUTS
The RGBHV- and DVI- outputs (#41, 43 and 37) of the Visualizers can be switched on and off
A constant sync signal is supplied to all switchable outputs (even in the image off mode) eliminating monitor image
distortions when switching the outputs on and off..
. Use the IMAGE key
(#17) to switch the signal supplied from these outputs on and off. Independently an image is always output by the
Preview (#40) and PAL/NTSC video outputs (#44 and #45). These outputs can be used for a control monitor.
When the output signal is switched off, the IMAGE key on the control panel is illuminated red.

The USB output of the VZ-27 and VZ-57 can be used to store still
images from the Visualizer in a computer. No additional computer
hardware (like a grabber card) is required. In this way the
Visualizer can be used as a 3-D scanner for your computer.
Just connect the USB port (#38) of the Visualizer and the USB port
of your computer. A dedicated WolfVision USB-scan-software is
available on the supplied CD-ROM. The latest version of this
software can be downloaded from WolfVision's Internet homepage
